Description
TECHNICAL FIELD
The present invention relates to exercise machines of the type
having multiple exercise units which operate in opposition to a
single set of weights.
BACKGROUND ART
A variety of exercise units have been used in exercise centers for
many years each having a set of weights lifted responsive to manual
force exerted for muscular development. The exerciser can normally
vary the amount of weight resisting the exercising effort. As the
need for compact exercise equipment has developed for use, for
example, in residences, attempts have been made to provide
arrangements in which multiple exercise units operate on a single
set of weights rather than providing an individual set of weights
for each exercise unit. One approach has been an arrangement in
which each exercise unit had to be connected to the weight set
whenever it was to be used and then disconnected when another of
the exercise units was to be used. Another approach has been to
connect to the single set of weights by a respective cable for each
exercise unit in such a manner that each of these cables is only
tensioned when the respective exercise unit is used. This usually
results in an arrangement in which the pull line of the cables when
tensioned is off center relative to the center of gravity of the
weight set.
With the foregoing shortcomings in mind, the present invention aims
to provide a simplified arrangement in which multiple exercise
units are continuously connected to a single weight set by a pulley
and cable system which only attached to the weight set by a single
centered cable.
DISCLOSURE OF THE INVENTION
In carrying out the invention, multiple exercise stations are
provided, each preferably incorporating more than one exercise
unit. Each exercise unit is connected to one of multiple cables
each of which is tensioned when one of the exercise units is used.
The cable connected to the weight set has an exercise unit at its
opposite end and passes over sets of floating pulleys through which
are reeved other cables each having exercise units at its ends.
Each cable end has a stop to prevent retracting of the cable so
that each cable in the system can be tensioned responsive to use of
one of the exercise units. Additional exercise units can be
incorporated by use of single floating pulleys on one of the cables
which are directly connected to an exercise unit. In some
instances, instead of connecting the end of a cable directly to an
exercise unit, it can be connected to a pulley which in turn has a
secondary cable reeved thereon and connected at its ends to an
exercise unit as, for example, a butterfly exercise unit having its
wings connected to the ends of the secondary cable.
In the preferred embodiment, three exercise stations are arranged
in a generally triangular configuration, with the weight set on a
base platform therebetween. Each station has two exercise units. A
hollow column houses part of the cable and pulley system and
provides a reach arm overlying the weight unit and a second reach
arm overlying one of the exercise stations. A first cable connects
to the weight set and is guided over the first reach arm into the
column where it is reeved through two sets of floating pulleys and
then is guided to the outer end of the second reach arm to connect
to one of the exercise units. Two other cables were reeved in the
column through the respective of the two floating pulley sets and
are guided out of the column to the exercise stations. A fourth
cable passes over a single floating pulley in the column and
connects at its ends to one of the exercise units.

BEST MODE FOR CARRYING OUT THE INVENTION
Referring to the drawings, the exercise machine of the present
invention has three exercise stations A, B and C at the apexes of a
generally triangular base frame 10. Each exercise station has two
exercise unit individually operative to lift weight in a weight
stack unit 11 resting on the base frame. For ease of explanation,
the exercise units 12-13 at station A are designated the "high pull
unit" and the "butterfly unit," the exercise units 14-15 at station
B are designated the "abdominal crunch unit" and the "leg
curl/extension unit," and the exercise units 16-17 are designated
the "press unit" and the "low pull unit."
The weight stack unit 11 is of standard construction, comprising a
stack of rectangular weights 11a which are slide-mounted on a pair
of vertical guide rods 11b, each weight having a central horizontal
hole registering with a respective hole in a central pick-up rod
11c. This pick-up rod depends from a head plate 11d which is also
slide-mounted on the rods 11b and has a lift cable 18 secured
thereto. The amount of weight to be lifted is selected by engaging
a lock pin 11e through the appropriate one of the weights 11a into
the pick-up rod 11c. Hence, when the cable 18 is adequately
tensioned, the selected number of weights in the stack is
lifted.
As shown in FIG. 2, the cable 18 functions in conjunction with
cables 19 and 20 by way of floating pulley sets 21-22 and 23-24,
the two pulleys in each of these sets being coupled together. Cable
18 is guided by five guide pulleys 25-29 and passes beneath the
floating pulley 21. The center pulley 27 is vertically adjustable
for slack take-up. Cable 19 passes over the floating pulley 22, is
connected to a floating pulley 30, and is guided by guide pulleys
31-32. Cable 20 passes over floating pulley 24, is guided by six
guide pulleys 33-38, and passes over a floating pulley 39 which is
connected to the lower end of a cable component 40 of the press
unit 16. Another cable 41 passes over the floating pulley 30 and is
guided by guide pulleys 42-43.
The high pull unit 12 is connected to one end of the cable 18, the
butterfly unit 13 is connected to the ends of cable 41, the leg
curl extension unit 15 is connected to one end of the cable 19, and
the abdominal crunch unit 14 and the low pull unit 17 are connected
to the ends of cable 20. The cable component 40 and the cables 18,
19, 20 and 41, have ball-like stop fittings 16a, 12a, 13a, 14a, 15a
and 17a, respectively mounted thereon to restrict retraction
thereof.
With the described pulley and cable arrangement it can be seen that
the tension in the three cables 18-20 is equal whenever one of them
is tensioned by operation of an exercise unit, that the tension in
the cable 41 is one-half the tension in the cables 18-20, and that
the downward pull force on the cable component 40 of the press unit
16 is twice the tension in the cables 18-20.
Adjacent the butterfly unit 13 and at one apex of the base 10 there
is mounted a column 44 having two reach arms 45, 46 mounted at its
upper end. Reach arm 45 projects above the weight stack 11 and is
connected to the upper end of the guide rods 11b. The guide pulleys
25, 26 are mounted at the outer and inner ends of the reach arm 45,
and the guide pulleys 28, 29 are mounted at the inner and outer
ends of the reach arm 46. Slack adjusting pulley 27 is mounted on
the lower end of a threaded rod 27a passing downwardly through a
top bracket 44a on the column 44 and having an adjusting nut above
the bracket.
The sets 21-22 and 23-24 of floating pulleys and the floating
pulley 30 float within the column 44, and the guide pulleys 42-43
for the cable 41 are mounted between two pairs of cheeks projecting
from the sides of openings in the column spaced above the lower end
thereof and facing the butterfly unit 13. At its lower end, the
column 44 has internal supports for the guide pulleys 31, 35. These
pulleys are in staggered relationship and guide the cables 19, 20
through openings in the column 44 toward station B. The column 44
has a third pair of cheeks projecting near the lower end thereof
from the sides of an opening to receive the guide pulley 36, which
is arranged to guide the cable 20 toward station C.
At station B, a cylindrical pedestal 47 is mounted on the base
frame 10 and has the pulleys 32 and 34 mounted in its lower end
with adjacent openings for the cables 19, 20. Another pedestal 49
is mounted on the base frame 10 for housing the floating pulley 39
below the press unit 16. The guide pulleys 37, 38 are mounted at
the lower end of the pedestal 49 at openings for entry of the cable
20 and exit thereof to make connection to the low pull unit 17
after passing over the floating pulley 39, which floats within the
pedestal 49 and is connected to the cable component 40 of the press
unit 16.
Directing attention to the butterfly unit 13 (FIG. 3), the ends of
the cable 41 pass out of the column 44 beneath the guide pulleys
42-43 and are anchored at the front of a pair of generally
horizontal cam members 48 which are located at opposite sides of a
pedestal 50 for a seat 51 having an upstanding back rest 52. The
pedestal 50 and back rest 52 are rigidly connected to the columnn
44 by suitable rear braces. A pair of brackets 53 project laterally
from opposite sides of the pedestal 50, and each supports a
depending pivot pin 54 on which a sleeve 55a is journal-mounted
which is connected to a swinging support rod 55 of generally
Z-shape for a respective padded wing 56. At its lower end, each
sleeve 55a is secured to a respective one of the cams 48. The pivot
pins 54 extend downwardly beyond the sleeves 55a to receive cotter
keys therethrough for retaining the wings 56 and related apparatus.
The stops 13a are fixed on the cable 41 so that they will engage
the column 44 at the exit openings for the cable 41 from the column
44 at the pulleys 42-43 and leave slack in the portions of the
cable 41 between the stops 13a and the cams 48 when the wings 56
are swung rearwardly toward the column 44 sufficiently to be out of
the way of an exerciser seated on the seat 51 and pulling down on
the overhead handlebar 58 of the exercise unit 12, in opposition to
the selected number of weights in the weight stack 11.
When an exerciser desires to perform the butterfly exercise after
seating on the seat 51, the exerciser swings the wings 56 forwardly
taking out the slack in the outer end portions of the cable 41, and
then swings the wings 56 forwardly by pressure of the forearms
applied at the back of the wings. This forward swinging motion
tensions the cable 41 over the outer surface of curved convex cams
48a at the back of the cam members 48 as they rotate with the wings
56 about the axis of the pivot pins 54 in opposition to the
selected number of weights in the weight stack 11. I is noteworthy
that the described arrangement makes it possible for the seat 51 to
be used for both the butterfly unit 13 and high pull unit 12
without the movable components of either unit being in the way of
the exerciser when not in use.
Continuing to station B (FIGS. 4 and 6), the pedestal 47 rigidly
supports a rearwardly sloped back support member 60 to which is
connected a padded back rest 61. The member 60 continues
horizontally at its lower end over the top of the pedestal 47 and
is straddled by the frame 62 of a seat assembly 63. The frame 62
extends upwardly forwardly of the seat to provide a pivot support
62a. The seat assembly has a padded seat 63a and is pivoted at 63b
so that it can swing upwardly to a generally vertical position, as
shown in FIG. 6, preparatory to performance of the leg curl
exercise. The back support member 60 supports the pulley 33 at the
top on a pulley bracket which is engaged by the stop ball 14a on
the respective end of the cable 20 when the exercise unit 14 is
idle. A pair of elongated strap loops 64 are connected to the end
of the cable 20 to function as part of the apparatus for the
abdominal crunch exercise.
Pivoted at an upper end to the back of the seat 63 is a link 65
which has its lower end bent at right angles to the rest of the
link to provide a stop 65a for cooperating with the underside of a
U-shaped bracket 66 mounted on the inside of the seat pedestal 47.
The link 60 extends through the bracket 66 and is formed with a
notch 65b to serve as a catch for fitting onto the upper end of the
seat pedestal 47 when the seat assembly 63 is swung upwardly so
that the seat assembly 63 cannot then swing down from the upright
position without the link 65 being lifted free of the seat pedestal
47 preparatory to swinging the seat back to a horizontal seating
position.
A dual-purpose element 70 of inverted T-shape having padded bottom
arms 70a is pivotally suspended at 68 from the pivot support 62a.
The cable 19 passes from the guide pulley 32 in the seat pedestal
45 forwardly through a front opening in the pedestal and connects
to the lower end of the dual-purpose element 70. The stop ball 15a
is fixed on the cable 19 to engage the outer face of the pedestal
when the dual-purpose element 70 is in a down position and a
releasable lock pin 72 passes through the pivot support 62 and
upper end of the dual-purpose element 70 so that the latter can be
selectively held in a fixed down position or be free to be swung
forwardly away from the seat pedestal 47. It will be noted that the
seat assembly 63 also has a pair of side handles 74 which are
laterally offset from the seat 63a and are positioned so that they
may be conveniently grasped by a rearwardly facing exerciser when
the seat occupies its horizontal or upright position.
The abdominal crunch exercise is performed when the seat assembly
63 is in its horizontal position, as shown in FIG. 4, and the
dual-purpose element 70 is locked against swinging movement by the
pin 72. The exerciser seats on the seat 63a, rests his back against
the back rest 61 with the loops 64 passing over his shoulders, and
positions his legs so the front of his ankles bear against the back
of the padded bottom arms 70a. Then the exerciser performs the
abdominal crunch exercise by grasping the loops 64 and pulling them
downwardly and outwardly away from the upper pulley 33 in
opposition to the selected load at the weight stack while keeping
his lower back against the back rest 61.
To perform the leg extension exercise, the exerciser unlocks the
dual-purpose element 70 by removing the pin 72 and then grasps the
handles 74 while seated. Using both legs, the exerciser pivots his
legs at the knee away from the seat pedestal 47, engaging the
padded arms 70a and forcing element 70 to swing forwardly in
opposition to the selected load at the weight stack 11.
Preparatory to performing the leg curl exercise, the seat assembly
63 is swung upwardly and locked in upright position by use of the
link 65, and the lock pin 72 is released so that the dual-purpose
element 70 is free to swing forwardly in opposition to the selected
load at the weight stack 11. As the seat assembly 63 swings
upwardly, the pivot 68 swings forwardly and lowers. In the raised
position of the pivot 68, the arms 70a of the dual-purpose element
70 are at the most suitable height for the leg extension exercise;
and when the pivot 68 is in its lowered position, the pivot 68 and
arms 70 are in the most suitable position for the standing leg curl
exercise. The exerciser faces rearwardly in standing position with
his legs behind the padded bottom arms 70a and grasps the upright
seat handles 74. Then the exerciser pivots one of his legs at the
knee away from the seat pedestal 47 so that the back of the ankle
of the leg engages the respective padded arm 70a and forces the
dual-purpose element 70 to swing forwardly away from the seat
pedestal 47 in opposition to the selected load at the weight stack
11. After swinging the leg back and forth the selected number of
times, the exercise is repeated with the other leg.
Continuing to station C, the cable 20 passes forwardly from the
guide pulley 38 (FIG. 5), through a front opening in the pedestal
49 and is connected, for example, to a pair of hand grips 17b for
performing a low pull exercise. The pulley 38 is preferably mounted
for swinging movement of about thirty degrees on a vertical axis.
The stop 17a on the cable 20 is arranged to engage a stop bracket
at the underside of the pulley 38 to restrict retraction of the
cable.
As previously indicated, the cable component 40 is connected to the
floating pulley 39 within the pedestal 49. It extends upwardly
through a center opening in a head plate 49a at the top of the
pedestal 49 and has the stop 16a arranged to engage the upper
surface of the head plate 49a when the press unit 16 is not in use.
The cable component 40 is connected at its upper end to a swing bar
80 having a forked rear end portion 80a which straddles the column
44 and is pivotally connected thereto at 81. The forward end of the
swing bar 80 has rigid fork extensions 80b which are bridged at
their forward ends by a handle bar 82. It is preferred that the
cable component 40 be connected to the swing bar 80 approximately
midway between the pivot 81 and the handlebar 82 so that the
exerciser has a 2:1 mechanical advantage when he pushes up on the
handle bar 82 in opposition to the load of the selected weights in
the weight stack 11 in performing the press exercise. This 2:1
mechanical advantage, by doubling the upward force exerted on the
pulley 39 for a given manual upward force exerted on the handle bar
82, results in substantially the same tension in the cables 18-20
as results when the same manual force is applied to the cables
18-20 at any one of the other exercise units. The function of stop
16a can be performed by having the handle 80 rest directly on the
pedestal 49.
To provide adjustment of the height of the handle bar 82 during
performance of the press exercise, the swing bar 80 is articulated
forwardly of the cable component 40 to provide rear and forward
swing bar sections 80a, 80b. The rear section 80a has a sector
plate 84 forwardly of the articulation. This plate has an arcuate
row of holes for selectively receiving a pin registering with a
hold through the front section 80b.
For body support while performing the press exercise, a bench
assembly 90 is provided at station C which comprises a pedestal 91
supporting the forward end portion of a bench frame 92. At its rear
end the bench frame 92 is pivotally mounited at 93 to the pedestal
49 for horizontal swinging movement so that the bench assembly can
be swung laterally out of the way when optional exercises are to be
performed using exercise unt 16 or a low pull exercise is to be
performed using grips 17b. In this regard, a resilient floor mat 94
connected to pedestal 49 may be provided for stability when
performing low pull exercises with exercise unit 17 or press
exercises with exercise unit 16 without use of the bench 90.
The bench assembly has padded adjustable back rest and seat rest
sections 95-96 swingably connected together. The back rest section
95 has a pair of pivoted links 98 pivotally connected to the frame
92 and the seat section 96 is slidable along the frame 92 for
adjusting the slope of the back rest section. Notches 92a in the
frame 92 are selectively engaged by a slide element 99 on the seat
section 96 to hold it in the horizontal position corresponding to
the desired slope, if any, for the back section 95.
It will be apparent that additional exercise stations can be added
incorporating the cable and pulley system concepts of the
invention. It is also apparent that sprockets and chains can be
substituted for the pulleys and cables of the system; hence, it is
intended that "pulley" and "cable" when used in the claims be
interpreted to include sprockets and chains or belts.
From the foregoing it will be appreciated that, although specific
embodiments of the invention have been described herein for
purposes of illustration, various modifications may be made without
deviating from the spirit and scope of the invention. Accordingly,
the invention is not limited except as by the appended claims.
